Description

[Technical field]

[0001] The present invention relates to an antifungal, deodorizing, and deodorizing agent. More specifically, the present invention relates to an antifungal, deodorizing, and deodorizing agent which has both an excellent antifungal effect and an excellent deodorizing and deodorizing effect and is easy to use. [Background technology]

[0002] Odors in waste storage spaces such as trash cans and diaper disposal containers have been a problem for some time, and various studies have been conducted to solve the problem. For example, cited reference 1 describes a deodorizer for the purpose of deodorizing waste storage spaces such as trash cans, in which porous spherical regenerated cellulose particles are impregnated with a deodorizing composition containing (a) iodine and (b) plant essential oils. Also, cited reference 2 describes a trash can equipped with a deodorizing or odor eliminating mechanism for food waste. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-65965 A [Patent Document 2] JP 2014-201396 A Summary of the Invention [Problem to be solved by the invention]

[0004] The deodorizer described in the above cited document 1 contains iodine as an essential ingredient, and there is a risk of discoloring the trash can depending on the material of the trash can, so it cannot necessarily be said to be suitable for deodorizing waste storage spaces such as trash cans.

[0005] In addition, the trash can described in the cited document 2 is an excellent one that has a deodorizing and odor eliminating effect on food waste, but it has a complicated mechanism and is difficult to use conveniently.

[0006] Therefore, there is a demand for the development of a deodorizing agent that has an excellent deodorizing effect in waste storage spaces such as trash cans, is suitable for use in trash cans, and is easy to use. [Means for solving the problem]

[0007] In order to solve such problems, the inventors conducted various studies and discovered that, in addition to deodorizing and removing odors from trash cans, the deodorizing and removing effect can be further enhanced by suppressing the growth of mold in addition to deodorizing and removing the bad odors themselves.

[0008] However, since the components that suppress the growth of mold are generally highly volatile, when they are adsorbed into the deodorant, not only does the effect of suppressing the growth of mold decrease, but the performance of the deodorant itself to adsorb malodors also decreases. As a result of intensive research, the present inventors have found that in an anti-mold deodorant having a first sheet-like substrate containing a room temperature volatile anti-mold component and a second sheet substrate containing a deodorant, the above-mentioned problems can be solved by specifying the density of the second sheet substrate within a certain range, and the anti-mold deodorant can have both excellent anti-mold effect and excellent deodorant effect, and can be used easily.

[0009] That is, the present invention relates to the following. [1] A method for manufacturing a smeared sheet-like substrate comprising: a first sheet-like substrate containing an ordinary-temperature volatile antifungal component; and a second sheet-like substrate containing a deodorizing agent, the density of which is 0.21 mg / mm 3 ~0.50mg / mm 3 The antifungal, deodorizing and deodorizing agent is characterized by: [2] The antifungal deodorizing agent according to [1], wherein the second sheet-like substrate is formed from a fibrous material. [3] The anti-mold, deodorizing, and deodorizing agent according to [2], characterized in that the fibrous material is one or more selected from the group consisting of natural cellulose, regenerated cellulose, bacterial cellulose, chemically modified cellulose, silk, wool, polyacrylamide, hemp, collagen, and wood wool. [4] The antifungal deodorizing agent according to [2] or [3], wherein the fibrous material has a fiber diameter of 10 to 150 μm. [5] The antifungal deodorizing agent according to any one of [1] to [4], wherein the room-temperature volatile antifungal component contains a room-temperature volatile antifungal compound having a boiling point of 290°C or less. Effect of the Invention

In addition, in the present invention, a menthane antifungal compound having a hydroxyl group is treated as a menthane antifungal compound rather than an alcohol antifungal compound.

[0020] It is preferable to use a mixture of one or more selected from ester-based antifungal compounds, one or more selected from alcohol-based antifungal compounds, and one or more selected from menthane-based antifungal compounds as the room temperature volatile antifungal component, since it can exert a stronger antifungal effect. In this case, the blending ratio of each component, (blended weight of ester-based antifungal compounds):(blended weight of alcohol-based antifungal compounds), is preferably 1:12-14:1, more preferably 1:7-8:1, and even more preferably 1:4-5:1.

[0021] The method of incorporating the room temperature volatile antifungal component into the first sheet-like substrate is not particularly limited as long as the volatility of the room temperature volatile antifungal component is not impaired. For example, the room temperature volatile antifungal component can be incorporated into the substrate by known methods such as printing using various plates, impregnation, immersion, spray coating, dropping, kneading into the substrate, etc., either as it is or in any combination with various resins, binders, solvents, etc.

[0022] In addition, various additives can be added to the first sheet-like substrate as desired within the scope of the object and effect of the present invention, which is to provide both an antifungal effect and a deodorizing effect. Examples of such additives include a volatilization regulator, a stabilizer, an antioxidant, a discoloration inhibitor, an ultraviolet inhibitor, and a fragrance such as a harmonized fragrance.

[0023] The second sheet-like substrate contains a deodorizing agent, and is preferably formed from a fibrous material containing a deodorizing agent. The density of the second sheet-like substrate is 0.21 mg / mm 3 ~0.50mg / mm 3 and 0.28 mg / mm 3~0.45mg / mm 3 It is preferable that:

[0024] The deodorizing agent contains one or more selected from the group consisting of activated carbon, plum charcoal, silica gel, activated alumina, zeolite, and ceramic, and therefore has excellent deodorizing and deodorizing effects without causing any adverse effects such as coloring or discoloration of the trash can during use. Among these, those containing one or more selected from the group consisting of activated carbon, plum charcoal, silica gel, and zeolite are preferred.

[0025] The deodorizing agent may contain metal ions such as copper ions, silver ions, calcium ions, lithium ions, potassium ions, sodium ions, and magnesium ions, and preferably contains copper ions or silver ions from the viewpoint of excellent deodorizing effect.

[0026] In the present invention, examples of the substrate used for the second sheet substrate include paper, woven fabric, nonwoven fabric, resin film, and laminates thereof. Among these, those formed from fibrous materials are preferred.

[0027] In the present invention, the method of incorporating the deodorant in the second sheet substrate can be, for example, to hold the deodorant directly or in any combination with various resins, binders, solvents, etc., on the substrate by known methods such as printing using various plates, impregnation, immersion, spray application, dropping, kneading into the substrate, etc. Note that a method can be adopted in which a sheet such as paper or nonwoven fabric is formed using a raw material containing the deodorant by known papermaking methods or known manufacturing methods such as spunlace, needle punch, airlaid, etc.

[0028] In the present invention, the second sheet-like substrate is preferably formed from a fibrous material containing the deodorizing agent.

[0029] In the present invention, examples of the fibrous material include natural cellulose (pulp, kenaf, cotton, hemp), regenerated cellulose (cellophane, cellulose beads, rayon, cellulose sponge, etc.), cotton, bacterial cellulose, and cellulose derivatives such as ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl hydroxyethyl cellulose, and carboxymethyl cellulose, which are chemically modified cellulose, as well as silk, wool, hemp, natural or artificial hydrophilic polymers such as polyvinyl alcohol, cross-linked polyvinyl alcohol, chitin, chitosan, ethylene vinyl acetate copolymer, and polyvinyl formal, highly water-absorbent polymer gels such as polyacrylamide, collagen, and wood wool, and the fiber diameter is preferably 10 to 150 μm, more preferably 30 to 100 μm, and even more preferably 40 to 90 μm.

[0030] In the present invention, the method of incorporating the deodorant into the fibrous material is not particularly limited as long as it does not use any solvent, binder, adhesive, or spreading agent or minimizes the amount of the solvent, binder, adhesive, spreading agent, etc. For example, a method of dispersing zeolite particles or the like into the fibrous material by impregnation, immersion, kneading, etc. can be used.

[0031] According to such a method, a sheet-like substrate holding a deodorizing agent can be obtained without using various solvents, binders, adhesives, or spreading agents, or by minimizing the amount of such used, so there is no problem in that the pores of the deodorizing agent in the sheet-like substrate are blocked by various solvents, binders, adhesives, or spreading agents, thereby inhibiting the deodorizing agent.

[0032] The method for forming the fibrous material into a sheet to obtain the second sheet-like substrate is not particularly limited, but for example, a method can be used in which the fibrous material is used to form a sheet of paper, nonwoven fabric, or the like by a known papermaking method or a known manufacturing method such as spunlace, needle punch, or airlaid.

[0033] The second sheet-like substrate 3 formed from the fibrous material containing the deodorant may be a commercially available product. Examples of such commercially available products include Celgaia (registered trademark) (manufactured by Rengo Co., Ltd.), plum charcoal crepe paper (product name: Sumideco Paper, manufactured by Sanyo Paper Co., Ltd.), activated carbon sheet (manufactured by Oji Kinocloth Co., Ltd.), zeolite sheet (manufactured by Oji Kinocloth Co., Ltd.), silica gel sheet (manufactured by Oji Kinocloth Co., Ltd.), FS-ZEO (registered trademark) (manufactured by Toppan Printing Co., Ltd.), and functional powder-supported nonwoven fabric (manufactured by Nippon Vilene Co., Ltd.).

[0034] In the present invention, in the manufacture of the antifungal deodorant, the first sheet substrate and the second sheet substrate may be laminated. They may be stored in the same storage section of the same container, or may be stored in different storage sections of the same container. From the viewpoint of breathability, it is preferable to store the first sheet substrate and the second sheet substrate in different storage sections of the same container. Examples of the container include a plastic molded container, a paper container, a bag-shaped object, etc.

[0035] The antifungal deodorizing agent of the present invention is suitable for use in waste storage spaces such as trash cans, diaper disposal pots, etc. Specific methods of use include pasting it on the inner wall of the waste storage space such as trash cans, diaper disposal pots, etc., or placing it in the waste storage space such as trash cans, diaper disposal pots, etc. From the viewpoint of ease of handling during use, it is preferable to use it by pasting it on the inner wall of the waste storage space such as trash cans, diaper disposal pots, etc. EXAMPLES

[0036] The antifungal deodorant of the present invention will be described in more detail below with reference to specific examples and test examples, but the present invention is not limited to these examples and test examples.

Then, a 20 cm 2 The opening and the 3cm opening that releases the anti-mold ingredients 2 The cover portion having the opening was attached to the main body to prepare an antifungal deodorizing agent, which was designated as Example 1.

[0038] [Examples 2 to 5, Comparative Examples 1 to 2] In Example 1, the second sheet-like substrate was changed to a second sheet substrate prepared to have the components and density shown in Table 1, and the rest was similar to Example 1 to prepare the antifungal deodorizing deodorants of Examples 2 to 5 and Comparative Examples 1 and 2, respectively.

[0039] [Table 1]

[0040] [Test Example 1] Deodorizing effect of ammonia In order to confirm the deodorizing effect of the antifungal deodorizing agent, the following deodorizing test 1 was carried out. Seven plastic cylinders (inner diameter 20 cm, height 20 cm) were prepared, 50 μL of ammonia water was added to each, and a glass plate with the antifungal deodorizing agent of Examples 1 to 5 and Comparative Examples 1 to 2 attached thereto was placed on top and covered. After adding 50 μL of ammonia water, the glass plate was placed on top and covered as an untreated control. These plastic cylinders were left to stand at room temperature (25°C) for 2 hours, and the odor of ammonia in the cylinder was measured with a gas detector tube (manufactured by Gastec Corporation). In addition, as an untreated group, the odor concentration of ammonia in a cup after standing for 2 hours was also measured with a gas detector tube under the same conditions as the above-mentioned treated group except that the drug-impregnated body was not hung. The deodorizing rate (%) was calculated from the measurement results based on the following formula (I) and rated on a four-level scale: A: 80% or more but less than 100%, B: 60% or more but less than 80%, C: 40% or more but less than 60%, and D: less than 40%. The test results are shown in Table 2.

[0041] (Number 1) Deodorization rate (%) = [1-odor concentration in treated area / odor concentration in untreated area] x 100 (I)

[0042] [Test Example 2] Deodorizing effect of trimethylamine In order to confirm the deodorizing effect of the antifungal deodorant, the following deodorant test 2 was carried out. Seven plastic cylinders (inner diameter 20 cm, height 20 cm) were prepared, 50 μL of trimethylamine was added to each, and a glass plate with the antifungal deodorant of Examples 1 to 5 and Comparative Examples 1 to 2 attached thereto was placed on top and covered. After adding 50 μL of trimethylamine, the glass plate was placed on top and covered as an untreated control. These plastic cylinders were left at room temperature (25° C.) for 2 hours, and the odor of trimethylamine in the cylinder was measured with a gas detector tube (manufactured by Gastec Corporation). In addition, as an untreated group, the odor concentration of trimethylamine in the cup after leaving it for 2 hours was also measured with a gas detector tube under the same conditions as the above-mentioned treated group except that the drug-impregnated body was not hung. The deodorizing rate (%) was calculated based on the measurement results in accordance with the above formula (I) and rated on a four-level scale: A: 80% or more and less than 100%, B: 60% or more and less than 80%, C: 40% or more and less than 60%, and D: less than 40%. The test results are shown in Table 2.

[0043] [Test Example 3] Deodorizing effect of methyl mercaptan In order to confirm the deodorizing effect of the antifungal deodorant, the following deodorant test 3 was carried out. Seven plastic cylinders (inner diameter 20 cm, height 20 cm) were prepared, 200 μL of methyl mercaptan was added to each, and a glass plate with the antifungal deodorant of Examples 1 to 5 and Comparative Examples 1 to 2 attached thereto was placed on top and covered. After adding 200 μL of methyl mercaptan, the glass plate was placed on top and covered as an untreated control. These plastic cylinders were left at room temperature (25° C.) for 2 hours, and the odor of methyl mercaptan in the cylinder was measured using a gas detector tube (manufactured by Gastec Corporation). In addition, as an untreated group, the odor concentration of methyl mercaptan in the cup after leaving it for 2 hours was also measured using a gas detector tube under the same conditions as the above-mentioned treated group except that the drug-impregnated body was not hung. The deodorizing rate (%) was calculated based on the measurement results in accordance with the above formula (I) and rated on a four-level scale: A: 80% or more and less than 100%, B: 60% or more and less than 80%, C: 40% or more and less than 60%, and D: less than 40%. The test results are shown in Table 2.

[0044] [Table 2]

[0045] As a result of Test Examples 1 to 3, the density of the second sheet-like substrate was 0.21 mg / mm 3 ~0.50mg / mm 3 The antifungal deodorants of Examples 1 to 5, in which the density of the second sheet-like substrate was 0.28 mg / mm 3 ~0.45mg / mm 3The antifungal deodorants of Examples 3 to 5 exhibited particularly excellent deodorant effects against ammonia, trimethylamine, and methyl mercaptan.

[0046] On the other hand, the density of the second sheet-like substrate is 0.21 mg / mm 3 The density of the sheet-like substrate in Comparative Example 1 or the second sheet-like substrate is less than 0.50 mg / mm 3 In Comparative Example 2, which exceeded the above range, the deodorizing effect against ammonia, trimethylamine, and methyl mercaptan was insufficient.

[0047] [Test Example 4] Test for suppressing putrid odor generation from food waste 1 Each food item (12 g of firefly squid, 35 g of radish, 40 g of cheese, and 35 g of pork) and 10 g of water were placed in a trash can with a lid (depth 45 cm, width 34 cm, height 58 cm). The mold-proofing deodorizing agent of Example 4 of the present invention was attached to the inside of the lid, and the lid was then closed. After storing the container at room temperature (25°C) for 7 days, the odor concentrations of ammonia, trimethylamine, and methyl mercaptan in the flask were measured using a gas detector tube (manufactured by Gastec Corporation). In addition, an untreated group was stored under the same conditions as the treated group above, except that the anti-mold and deodorizing product was not attached to the underside of the lid. The odor concentrations of ammonia, methyl mercaptan, and trimethylamine in the flasks after storage for 7 days at room temperature (25°C) were also measured using a gas detection tube (manufactured by Gastec Corporation). The putrid odor generation inhibition rate (%) was calculated based on the measurement results and the formula (I) described above. (The test results are shown in Table 3.)

[0048] [Table 3]

[0049] As a result of the test, it was confirmed that the antifungal deodorizing agent of the present invention exhibits a putrid odor generation suppression effect.Furthermore, when the appearance of each food was compared between the untreated and treated food after 7 days of storage, mold was generated in the untreated food, whereas mold was not generated in the food (treated food) using the antifungal deodorizing agent of the present invention, and it was confirmed that the antifungal deodorizing agent of the present invention has an excellent antifungal effect. [Industrial Applicability]

[0050] The antifungal, deodorizing and deodorizing agent obtained by the present invention has both an excellent antifungal effect and an excellent deodorizing and deodorizing effect, and furthermore, can be used easily, and is therefore extremely useful.
